Fractyl Health reports positive 6-month results from its REVEAL-1 Cohort study on post-GLP-1 weight maintenance.

Participants who lost 24% total body weight on GLP-1 drugs maintained stable weight 6 months after discontinuation and a single Revita procedure.

New data highlights Revita's potential as a pioneering therapy for post-GLP-1 weight maintenance.

Sustained Weight Maintenance

Participants maintained stable weight with a mean total body weight change of 1.5% after a single Revita procedure.

Sustained Glycemic Control

Minimal change in HbA1c levels post-Revita, indicating potential for stabilizing cardiometabolic parameters.

Stable Metabolic Trajectory

Consistent body weight and HbA1c trajectories over 1, 3, and 6 months suggest durable metabolic control with Revita.

Excellent Tolerability

No serious adverse events related to the procedure, with mild transient events observed in a small percentage of participants.

Reproducible Procedure Performance

Ablation length consistent with prior experience, supporting potential scalability and translation of results.

  • The results demonstrate a potential off-ramp from GLP-1 drugs for patients seeking long-term metabolic health.
  • Revita's positive outcomes offer a new strategy for weight and metabolic maintenance post-GLP-1 therapy discontinuation.

The REVEAL-1 study outcomes signify a significant advancement in understanding the efficacy of Revita for sustained weight and metabolic control post-GLP-1 therapy. Fractyl Health's dedication to innovative approaches in obesity and diabetes treatment is evident in these promising results.
